If you don't know who Charlotte McKinney is yet, you should by the time the Super Bowl is over on Sunday. The 21-year-old model and Instagram celebrity landed the lead in this year's Carl's Jr. ad, a spot that sees her strolling clotheslessly through a farmer's market to promote the fast-food chain's new "all-natural," grass-fed-beef burger. Esquire spoke with McKinney ahead of the Super Bowl about how many bites she actually took, her future plans, and getting hit on at Whole Foods.

ESQUIRE.COM: So how did you score this Carl's Jr. commercial?

CHARLOTTE MCKINNEY: They saw my Fox interview and my social-media pages, and then they reached out to my agent.

ESQ: You didn't even have to audition?

CM: No, there wasn't really an audition process. They just booked me.

ESQ: What was it like to shoot it?

CM: It was exciting. It was all done in one day and they treated me so well.

ESQ: How many takes did you have to do?

CM: We did a lot of takes. When we first did it they had me saying the lines during the commercial. And then they decided they didn't want me saying it and they wanted voiceover. It was a long day.

ESQ: Did you actually take real bites of the burger?

CM: I went for it! I bit into that burger. They want it to look as real as it can. I definitely got in there. They said usually most of the girls take a lot of bites, but I only did eight. My best bite was my first one. I only took eight bites. I'm a fan of Carl's Jr. though. I'm from Florida and we didn't have it out there, so when I came to LA it was definitely a choice I made to eat it.

ESQ: Is there a good burger in Florida?

CM: The best burger in Florida would have to be my mom's. My mom can pan-fry a burger like no other.

CM: Yeah, it was funny because I've always seen the commercials and thought, "Hey, I could do that. That looks fun." But it's such an iconic commercial, with Heidi Klum and Paris Hilton. To me, that was awesome. People talk about it in movies. It was such an honor to get that spot. I wasn't nervous though. The way I handle tough jobs is to not think about it and try to take it one step at a time. I didn't even think it was going to be in the Super Bowl. It was just another day at work. That's what I say to anyone who gets nervous: Just take it as it comes.

ESQ: So if last time you said you wanted to do Guess, who do you want to predict you'll do next?

CM: The next job I'd like to hit... I don't know. I'm really getting into acting and TV. Sports Illustrated is a big, iconic brand I'd like to work for, too. But TV and acting is really funny and a bit more exciting than shooting all the time.

ESQ: Have you acted in a TV show or movie yet?

CM: I've done some TV. I did a little skit on Tosh.0. And then I have a movie coming out with David Spade called Joe Dirt 2. That was so much fun to shoot. He was great.

ESQ: Wait—there's a sequel to Joe Dirt coming out?

CM: Yeah! It's going to be good. I play a logger named Missy. You'll just have to see it for yourself. I don't want to spoil it all now. It will be out this summer.

ESQ: As you've been building your career, who has given you the best advice on what to do and what not to do?

CM: A good friend of mine who I've known for a while told me who I should sign with and who is good and who is bad. Mostly I get advice from friends I've known for a while. I'm pretty picky when it comes to friends. I have to know them for a while. And I have a good family behind me, too.

ESQ: Everyone is calling you the next Kate Upton. How do you feel about that?

CM: It's pretty obvious. We both have blonde hair, we're from Florida, and we have enormous tits. It's super-flattering to me. Her career is amazing. But I'm ready to get that tossed away and start making a name for myself. Hopefully we both have a totally different realm of what we're doing. But it is flattering.

ESQ: What's something people wouldn't know about you from a photograph?

CM: They wouldn't know how funny I am. I can really stir up a conversation. Every time I go to a meeting or a casting, I try to make it as light and funny as I can. I'm always making really awkward jokes. You have to make life fun and not take it too seriously. I may look like I'm very serious and into my work, but if you knew me, I'm just a jokester. You can't look too serious walking around naked in a farmer's market eating a burger, but somehow I did.

ESQ: How naked were you actually?

CM: I was pretty close. I was in a nude bra and underwear all day. And then a bikini and shorts. The crew was awesome. They made me feel comfortable.

ESQ: It's almost like that dream where you end up naked in a public place.

CM: Yes! It's everyone's nightmare. But for me it was just another day.

ESQ: When you're not working, what do you like to do?

CM: I love fitness, yoga. I love fashion. On the weekends I try to relax. I have pretty crazy weeks. I like spas and nice dinners. I'm not much of a club person. I like to hang on the beach in Malibu.

ESQ: I was going to ask you for your favorite restaurants in L.A. and then I realized that might encourage stalking.

CM: Yeah, maybe we shouldn't say my favorite restaurants. But I love sushi. You'll always find me at a good sushi spot. Once at a restaurant a cook came out from the kitchen and asked for a picture with me. That was flattering. There's been nothing crazy yet, but I get some e-mails and Instagram messages that are a little out there.

CM: Surprisingly, they're not. I don't know where they get the nerve half the time! A lot of random people think they have a chance. Every time I go to Whole Foods I get someone's number because I feel bad. I'm really nice about that stuff, but it's really awkward.

ESQ: What's the worst pick-up line someone has tried on you?

CM: One time I was driving in Miami and I got to a gas station. A guy pulled up next to me and he goes, "If you drive like that, I'd love to get your number. You're just so aggressive." He asked to take me to dinner. I was like, "Over my driving? Sure." But I didn't go out with him. I thought that was kind of clever. He must have seen me driving for a while.

ESQ: Do you mean clever or creepy?

CM: It's probably more creepy!

ESQ: So now that you have a Super Bowl commercial, do you have plans to watch this weekend?

CM: Yeah, I'm going to watch it, but it's all up in the air where I'll be.

CM: Yeah. But that was the one and only time I'll really feed into it. Next time I'll never really talk to the guy. But I want to show that I'm approachable here and there. We know what we sign up for before we do something like this so you have to give the press some attention.

ESQ: Is there anything else you want people to know about you at this point?

CM: Everyone thinks I'm 22. But I'm 21. Every article says I'm 22. Also, I'm really easy-going. I'm not what everyone thinks a model is. I'm trying to change the perception, that we're not all these bratty girls. I'm a nice person. I'm a good friend.

ESQ: You're really trying to justify yourself.

CM: We get a bad name! Everyone's saying I put feminism back four decades, but if you can't take a joke, then don't watch it.
